Detailed Description

UniformQuantizer implements an uniform quantization scheme.

It divides the feature space into equally spaced bins.

Constructor & Destructor Documentation

prapi::UniformQuantizer::UniformQuantizer (  int    lev, double    origMax, double    origMin = 0.0 )  [inline]

Create a new UniformQuantizer instance. Example: UniformQuantizer q(64,256); //drop two lsb's of 8-bit feature values Parameters: lev  the number of quantization levels origMax  the original maximum value of the data. Add a small value (one quantization step in the original feature space) to this to prevent the quantizer from producing bin index lev. Typically, one is added when quantizing integer spaces. origMin  the original minimum value. Use the exact value.

Member Function Documentation

int prapi::UniformQuantizer::getBinIndex (  double    value )  throw (QuantizationException&) [inline, virtual]

Get the bin index for the given value, i.e. quantize the value. Returns: the quantized value Implements prapi::Quantizer.
